BACKGROUND OF THE INVENTION

Field of the Invention

The present invention generally relates to an activity monitoringsystem, and in particular to an athletic activity monitoring system thatfacilitates live monitoring of a plurality of individuals.

Background Art

Exercise is important to maintaining a healthy lifestyle and individualwell-being. A common way for individuals to exercise is to participatein athletic activities, such as, for example, sports and trainingprograms. A session of athletic activity may include, for example, atraining session or a competitive session such as, for example, a soccermatch or basketball game. When participating in athletic activities in acompetitive or collaborative environment, one's performance may bedependent on the performance of other individuals. For example, in ateam sport context, the performance of various athletic movements andendeavors may be influenced by the athletic movements and endeavors ofteammates or adversaries. Often, a trainer (e.g., a coach) is monitoringsuch athletic activity.

To effectively monitor the athletic activity, the trainer, or otherindividual, typically gathers information about the participants in theathletic activity by viewing the athletic activity from, for example,the sidelines of a sports field. Thus, the information used to makedecisions that influence the athletic activity is typically limited bywhat is observed by the trainer from the sidelines. A trainer may haveassistants to help with this observation, or multiple trainers may worktogether, however there remains difficulty in monitoring a plurality ofindividuals so as to effectively track and manage performance ofindividuals during an athletic activity.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described in detail with reference toembodiments thereof as illustrated in the accompanying drawings.References to “one embodiment”, “an embodiment”, “an exemplaryembodiment”, etc., indicate that the embodiment described may include aparticular feature, structure, or characteristic, but every embodimentmay not necessarily include the particular feature, structure, orcharacteristic. Moreover, such phrases are not necessarily referring tothe same embodiment. Further, when a particular feature, structure, orcharacteristic is described in connection with an embodiment, it issubmitted that it is within the knowledge of one skilled in the art toaffect such feature, structure, or characteristic in connection withother embodiments whether or not explicitly described.

The term “invention” or “present invention” as used herein is anon-limiting term and is not intended to refer to any single embodimentof the particular invention but encompasses all possible embodiments asdescribed in the application.

Various aspects of the present invention, or any parts or functionsthereof, may be implemented using hardware, software, firmware, tangiblecomputer readable or computer usable storage media having instructionsstored thereon, or a combination thereof, and may be implemented in oneor more computer systems or other processing systems.

Individuals participating in an athletic activity and trainers (e.g., acoach, physician, or other authorized individual) may work togetherduring a session of athletic activity for a variety of reasons. Forexample, it may be desired that the trainer monitors the performance ofthe individuals and makes recommendations or otherwise influences theirperformance in order to maximize the individuals' fitness level.Alternatively or additionally, it may be desired that the trainermonitors and influences the individuals to help maximize theeffectiveness of the individuals in the athletic activity. Further, itmay be desired that the trainer monitors and influences the individualsto help maximize the probability of success in the athletic activity(where success may be, for example, defeating an opposing team in agame, such as, for example, soccer, or achieving/maintaining a desiredlevel of fitness for one or more individuals participating in theathletic activity). A session of athletic activity may include, forexample, a training session (e.g., a field session, a gym session, atrack session) or a competitive session (e.g., a soccer match or abasketball game)

In some exemplary embodiments, the trainer may monitor and influence theindividuals in order to track and maintain the individuals' health andsafety. In such an embodiment, it may be beneficial for the trainer tobe provided with information relating to health and safety, for example,injuries, illnesses, and dangerous conditions.

The trainer must consider these and other goals, monitor theindividuals, and make decisions to influence the performance of theindividuals both individually and as a group. In doing so, the trainerdepends on information about the individuals and their performance whileparticipating in a session of athletic activity. The trainer may benefitfrom receipt of information in addition to that which is directlyobservable by the trainer. A group monitoring system according to anexemplary embodiment of the present invention can provide the trainerwith easy-to-understand information about individuals participating inthe athletic activity, beyond that which can be directly observed,thereby facilitating quick and effective decision-making by the trainerto maximize the probability of achieving success in the athleticactivity. In an exemplary embodiment, the group monitoring system canprovide alerts to the trainer to flag critical or important conditionsthat the trainer would not otherwise be able to observe directly, suchas, for example, fatigue of an individual or heart rate of an individualbeing above a threshold value.

In an exemplary embodiment, group monitoring system 100, depicted in,for example, FIGS. 1 and 11, includes individual monitors 200 (see FIG.2), a base station 300, and at least one group monitoring device 400(see FIG. 3). Individual monitor 200 may be coupled to an individual 10,as shown in FIG. 2. Individual monitor 200 may include or be incommunication with a variety of sensors 202, including, but not limitedto, an accelerometer, a pedometer, a heart rate monitor, a positionsensor, an impact sensor, a camera, a magnetometer, a gyroscope, amicrophone, a temperature sensor, and a wind sensor. In an exemplaryembodiment, individual monitor 200 may include a sensor garment 204, aheart rate monitor 206, and a position sensor 208. Position sensor 208may include, for example, a position sensor for use with asatellite-based positioning system (e.g., GPS (global positioningsystem)), a position sensor for use with a beacon system (e.g., positiondetermination using triangulation and/or time differences of signalsreceived by antennas at known positions about a field or activity area),or a position sensor for use with any other suitableposition-determining system. In some exemplary embodiments, groupmonitoring device 400 may be used by a trainer 20, as shown in FIG. 3.In an exemplary embodiment, individual monitor 200 may include amonitoring system such as, for example, those disclosed in U.S. patentapplication Ser. No. 12/467,944 and U.S. patent application Ser. No.12/467,948, each of which is incorporated herein in its entirety byreference thereto.

Generally, sensors 202 are mounted to individuals 10 in preparation forparticipation by individuals 10 in a session of athletic activity.Sensors 202 mounted to a particular individual 10 are coupled, eithervia wires or wirelessly, to individual monitor 200, also mounted on theparticular individual 10. Sensors 202 sense characteristics aboutindividual 10 during participation by individual 10 in the session ofathletic activity, and transmit data indicative of the characteristicsto individual monitor 200. Individual monitor 200 in turn transmits thedata to base station 300 during the session of athletic activity.

In some exemplary embodiments, this transmission occurs in real time.“Real time” as used herein may include delays inherent to transmissiontechnology, delays designed to optimize resources, and other inherent ordesirable delays that would be apparent to one of skill in the art. Insome exemplary embodiments, this transmission is delayed from real time,or may occur after completion of the activity. Base station 300 receivesthe data and determines metrics from the data, where the metrics may berepresentations of the characteristics measured by sensors 202, or maybe representations of further characteristics derived from the datathrough the use of algorithms and other data manipulation techniques.Base station 300 in turn transmits the metrics during the session ofathletic activity to group monitoring device 400, which receives themetrics and displays a representation of the metrics.

Group monitoring device 400 may receive metrics associated with aplurality of individuals 10, and may display the received metrics inassociation with the individual 10 with which they are associated. Inthis way, trainer 20 viewing group monitoring device 400 during thesession of athletic activity receives detailed information aboutmultiple individuals 10, and can act on that information as it isdetermined necessary or expedient, thereby efficiently monitoring andmanaging individuals 10 during the session of athletic activity.

In some exemplary embodiments, individual monitors 200 calculate metricsbased on the data, and transfer these metrics to base station 300 alongwith or instead of the data. In some exemplary embodiments, base station300 transmits the data to group monitoring device 400, along with orinstead of the metrics. In some exemplary embodiments, group monitoringdevice 400 calculates metrics based on the data.

In an exemplary embodiment, as shown in FIG. 4, individual monitor 200includes a battery 212, a data port 214, a position module 216, a heartrate monitor module 218, a controller 220, a user interface 222, atransceiver 223, an antenna 224, an acceleration sensor module 226, amemory 228, a gyroscope module 230, a magnetometer module 232, and atemperature sensor module 233. The sensors and corresponding modulesdiscussed herein are exemplary only; other sensors and modules can beused in conjunction with embodiments of the present invention. Battery212 can provide power to individual monitor 200 and may be, for example,built into individual monitor 200 or removable from individual monitor200, and may be rechargeable or non-rechargeable. Data port 214 canfacilitate information transfer to and from individual monitor 200 andmay be, for example, a universal serial bus (USB) port. In someexemplary embodiments, data port 214 can additionally or alternativelyfacilitate power transfer to battery 212, in order to charge battery212. As will be appreciated, transceiver 223 may include datatransmitting and receiving capability and may include a single componentor separate components.

Elements of individual monitor 200 may interconnect with one anotherusing a variety of techniques, such as, for example, wires, printedcircuit boards, wireless communications technology, serial ports, serialperipheral interfaces, other connection techniques, or a combinationthereof. Each individual monitor 200 is portable with respect to basestation 300 and can be carried by an individual 10 participating in anathletic activity. Individual monitor 200 may itself include sensors202, and/or may be in communication with sensors 202 carried byindividual 10 and located remotely from individual monitor 200. Eachindividual monitor 200 can be paired with base station 300 andassociated with an individual 10. Each individual monitor 200 mayinclude a unique identifier. The unique identifier may be, for example,a number imprinted on a viewable surface of individual monitor 200, ordata communicated or displayed when a button is pressed on individualmonitor 200 or when a request signal is received from base station 300.

To be paired with base station 300, individual monitor 200 can bereceived by a docking port 318 of base station 300 (see, e.g., FIG. 23).Base station 300 can then record the individual monitor 200 uniqueidentifier and can assign a unique encryption key to individual monitor200. This encryption key can be used to support secure transmission ofdata during the session of athletic activity. Such secure transmissionof data may be, for example, from individual monitors 200 to basestation 300, from base station 300 to individual monitors 200, and fromone individual monitor 200 to one or more other individual monitors 200.The encryption key can be renewed when required or desired (e.g., at thebeginning of each new session of athletic activity).

In some exemplary embodiments, assigning of individual monitors 200 toindividuals 10 can be facilitated by use of group monitor device 400, asdepicted in, for example, FIG. 53. For example, display 402 of groupmonitor device 400 may display a team or other group of individuals 10,along with monitor identifying information 242 (indicative of the uniqueidentifier of an individual monitor 200) of individual monitors 200associated with individuals 10. A user of group monitor device 400 maychange this association by selecting the identifying information 242 ofa particular individual monitor 200 associated with an individual 10,and inputting identifying information 242 of a different individualmonitor 200 to be associated with the individual 10. Display 402 mayalso display an indication of the connectivity or signal strengthbetween individual monitors 200 and base station 300.

Via an administrative interface 320 of base station 300, (which may be,e.g., an input and display located on base station 300, or which may beincorporated into a remote device such as, e.g., group monitoring device400 or analysis device 600) identification information of individual 10(e.g., individual 10's name and/or jersey number) can be associated withthe unique identifier of the individual monitor 200 to be carried byindividual 10. Once properly paired with base station 300 and associatedwith individual 10, individual monitor 200 can be removed from dockingport 318 and mounted on individual 10. Any external sensors 202 can bemounted on individual 10 and connected to individual monitor 200.

In an exemplary embodiment, such as that depicted in FIG. 7, individualmonitor 200 is a pod-like device and includes a position module 216 fordetermining data indicative of the location of individual monitor 200(and thus the location of individual 10 carrying individual monitor200), a heart rate monitor module 218 for determining data indicative ofthe heart rate of individual 10, a three-axis acceleration sensor module226 for determining data indicative of the acceleration of individual10, a gyroscope module 230 for determining data indicative of theorientation of individual 10 with respect to, for example, a playingfield and/or base station 300, and a magnetometer module 232 forcalibrating body motion data determined by gyroscope module 230 andacceleration sensor module 226. Each of position module 216, heart ratemonitor module 218, acceleration sensor module 226, gyroscope module230, and magnetometer module 232 may themselves include associatedsensors (e.g., a GPS sensor, a heart rate sensor, an accelerationsensor, a gyroscope, and a magnetometer, respectively), or may be incommunication with such an associated sensor. Such communication may bewired or wireless. In the case of wireless communication, each modulemay be communicatively paired with an associated sensor, to avoidmiscommunication and interference due to communication of othercomponents. In some exemplary embodiments, some or all of these andother modules may be included in a single module.

In an exemplary embodiment, some or all of sensors 202 are incorporatedinto sensor garment 204. In such an embodiment, sensors 202 incorporatedinto sensor garment 204 may connect to individual monitor 200 via wiresalso incorporated into sensor garment 204.

During participation by individual 10 in the session of athleticactivity, sensors 202 sense various characteristics of individual 10,generate data indicative of those characteristics, and transmit thatdata to memory 228 of individual monitor 200, where it is stored.Contemporaneously, individual monitor 200 wirelessly transmits the datato base station 300. The resolution at which the data is stored inmemory 228 and at which the data is transmitted to base station 300 maybe different, in order to optimize bandwidth, to optimize battery life,or for any other reason. For example, the heart rate of individual 10may be sampled by heart rate monitor module 218 at 200 Hz, and dataindicative of the heart rate may be generated at 200 Hz and stored inmemory 228 at 200 Hz, but may be transmitted wirelessly to base station300 at 2 Hz during the athletic activity. In some embodiments memory 228is sufficient to store data from a single session of athletic activity(e.g., 3 hours of data collection), and in some embodiments memory 228is sufficient to store data from up to 5 sessions of athletic activity(e.g., up to 15 hours of data collection).

Acceleration sensor module 226 can determine data indicative ofacceleration, which can be used in calculating, for example, speed,distance, and metrics that will be discussed below. In some exemplaryembodiments, the data indicative of acceleration can be used to increaseaccuracy of position data by, for example, using an accelerometer as astep counter or to determine a filter for a GPS signal calculation. Insome exemplary embodiments, the data indicative of acceleration can beused, in conjunction with pattern recognition software, to determine theactivity (e.g., the sport, movement, and/or drill) that an individual 10is performing.

Additionally, acceleration sensor module 226 can be used in conjunctionwith magnetometer module 232 and gyroscope module 230 in order tocalibrate body motion determinations. For example, informationindicative of impact, change in motion, gravity, and step counting canbe obtained using acceleration sensor module 226. Angular movement canbe obtained using gyroscope module 230, and the absolute “North”orientation can be obtained using magnetometer module 232. These sensorreadings can be used to determine, for example, the posture of anindividual 10, gravity, orientation of individual 10 in space, andheading of individual 10.

Position module 216 may determine data indicative of absolute positionat, for example, 10 Hz. Acceleration sensor module 226 may determinedata indicative of acceleration at, for example, 200 Hz. Gyroscopemodule 230 may determine data indicative of change of position andorientation at, for example, 200 Hz. Magnetometer module 232 maydetermine data indicative of orientation at, for example, 200 Hz. Datamay be transmitted from individual monitor 200 (via antenna 224) to basestation 300 using a radio frequency (RF) link. The RF link betweenindividual monitor 200 and base station 300 should be sufficientlyrobust to cover the expected area of the athletic activity (e.g.,playing field 30). In some exemplary embodiments, the RE link issufficient to cover a distance of 50-300 meters under all operatingconditions. In some exemplary embodiments, the RF link uses a globallyavailable, license-free band (e.g., the 2.4 GHz frequency). In someexemplary embodiments, the RF link is configurable to cover multiplelicense-free bands used throughout the world. As will be described ingreater detail below, in some exemplary embodiments base station 300 iscapable of using the RF link to link to a plurality of individualmonitors simultaneously, for example, up to 25 individual monitors 200,or up to 30 individual monitors 200.

Individual monitor 200 may be, for example, a pod-like device, as shownin FIGS. 5-7, including a plastic housing 234 that contains componentsof individual monitor 200, such as the modules discussed above, forexample. Individual monitor 200 may include connectors 236 that canprovide connection to conductors to removably connect individual monitor200 to, for example, sensors 202. Connectors 236 may removably connectto sensors 202 via, for example, snaps, clips, latches, or any othersuitable technique. Individual monitor 200 may further include an input238, which may be a button and which may function to turn individualmonitor 200 on or off, when appropriately manipulated. Input 238 mayinclude a background light indicator, which may be, for example, one ormore light emitting diodes (LEDs) that indicate qualities of individualmonitor 200. Such qualities may include, for example, state of operation(e.g., on, off, active, inactive, charging, low battery), memory status,and battery status. In some exemplary embodiments, individual monitor200 includes a visual display, such as, for example, a liquid crystaldisplay (LCD) screen, that can display this and other information.

Individual monitor 200 may further include a docking port 240, whichfacilitates wired communication with base station 300, and which canfacilitate charging of battery 212 of individual monitor 200, whenindividual monitor 200 is docked with base station 300. Housing 234 ofindividual monitor 200 may be sized so as to accommodate components ofindividual monitor 200 while minimally interfering with individual 10'sperformance of the athletic activity. Housing 234 may be sized, forexample, to fit into a pocket or cavity of a garment (e.g., sensorgarment 204). In some exemplary embodiments, dimensions of housing 234do not exceed 70 mm by 55 mm by 11 mm.

In some exemplary embodiments, housing 234 is water resistant, and allopenings (e.g., docking port 240, connectors 236) are sealed while inuse during athletic activity. Such water resistance can be achieved by aclose fit between exposed parts of individual monitor 200 (particularlyhousing 234), by use of plugs (e.g., plastic or rubber) that fit intoopenings, by use of a water resistant sealing compound, by othertechniques, or by any combination thereof.

Individual monitor 200 may include data processing capabilities, such asraw data reduction and filtering. For example, controller 220 may beconfigured to receive raw data from sensors 202 and to process such dataat the individual monitor, prior to transmission to base station 300.For example, rather than transmitting raw data representing electricalactivity sensed by heart rate monitor sensor 206, controller 220 ofindividual monitor 200 may process the raw data to calculate heart rate,number of heart beats in a given period, or other metrics of interest,which can be transmitted to base station 300. In some exemplaryembodiments, controller 220 of individual monitor 200 may use a uniqueencryption key (assigned by data processing module 304 of base station300) to encrypt data in order to securely transmit such data to basestation 300. Such processing of data at individual monitor 200 is notnecessary, however, and raw data can be transmitted directly to basestation 300 without such processing.

Operation of individual monitor 200 may be controlled by software storedin individual monitor 200 (e.g., stored in memory 228). This softwarecan be updated when necessary or appropriate. Software can be updatedvia communication with base station 300, which may send software updatesto individual monitor 200 wirelessly. Alternatively or additionally,software of individual monitor 200 may be updated through directconnection with base station 300 via docking ports 318 (as will bedescribed below), such that firmware of individual monitor 200 may beflashed appropriately.

Sensors 202 are selected and configured to provide a basis fordetermination of metrics of the individual 10 with which they areassociated. As used herein, “metrics” may refer to representations ofcharacteristics relevant to individual 10 or one or more groups ofindividuals 10, and may be, for example, physiological-, performance-,or location-based. A “metric” may simply be a representation of acharacteristic sensed by one of sensors 202, or may be a representationof a quality derived from data indicative of characteristics measured byone of sensors 202. For example, an acceleration sensor 210 sensesacceleration, and provides data indicative of this characteristic. Thisdata can be represented as a metric. Additionally, this data can befurther processed to determine further metrics such as velocity,direction of acceleration, and distance. Processing involving formulasand algorithms that work on the data received from sensors 202(including data from different sensors 202) and other sources can beused to determine a wide variety of metrics determined to be useful totrainer 20, including custom-designed metrics. Metrics can provideuseful information individually about multiple individuals 10, and canprovide useful information about groups of individuals 10. Metrics canalso take into account attributes of a particular individual 10 or groupof individuals 10, such as, for example, height, weight, endurance, andtop speed.

Base station 300 may be a self-contained portable system, such as theexemplary embodiments depicted in FIGS. 21-26, containing all hardwarerequired or desired to perform the functions of base station 300described herein. In some exemplary embodiments, base station 300 weighsno more than 25 kilograms. In some exemplary embodiments, base station300 is sized so as to fit easily into the trunk of a car or the overheadstorage area of a passenger aircraft. In some exemplary embodiments,base station 300 includes a pair of wheels 322 at one end, and a handle324 at the other end, to facilitate mobility of base station 300. Insome exemplary embodiments, base station 300 is waterproof, and canwithstand impacts associated with regular use and transport. In someexemplary embodiments, base station 300 is contained within a hardshell-style case 326. In some exemplary embodiments, base station 300 iscontained within a soft duffel bag-style case 328.

In some exemplary embodiments base station 300 is configured to beportable. In some exemplary embodiments, base station 300 is configuredto be positioned at an activity site. In some exemplary embodiments basestation 300 is configured to be movable between activity sites such thatit can be positioned at various activity sites. In some exemplaryembodiments base station 300 is configured to be portable with respectto at least one of individual monitors 200 and group monitoring device400. In some exemplary embodiments base station 300 is configured to beportable with respect to both individual monitors 200 and groupmonitoring device 400.

In some exemplary embodiments, base station 300 itself includes sensors,such as, for example, a GPS sensor (or other position sensor), agyroscope, a magnetometer, a temperature sensor, a humidity sensor,and/or a wind sensor. Such sensors can provide valuable data that can beused in algorithms to determine metrics associated with individuals 10,as will be described below.

In some exemplary embodiments, base station 300 includes a referencesensor 334 (e.g., a GPS reference sensor), which may be physicallyincluded within base station 300 or independent of and located remotefrom base station 300 at a known position with respect thereto.Reference sensor 334 can be connected to base station 300 via wires orwirelessly. Reference sensor 334 can be used to detect a deviationsignal and use it to calculate a correction signal for received positionsignals (e.g., GPS data). This correction signal can be sent toindividual monitors 200 (e.g., via base station 300). This correctionsignal can be used to correct position determinations of individualmonitors 200, thereby increasing their accuracy. Determining such acorrection signal and then sending it to individual monitors 200achieves efficient use of processing capacity, because individualmonitors 200 are not burdened with determining a correction signalthemselves, but simply receive and use a correction signal determined atbase station 300 or reference sensor 334.

Base station 300 may transmit and receive data from individual monitors200 via an antenna 330 configured for one or more of R communication,WLAN communication, ISM communication, cellular (e.g., GSM broad band2.5G or 3G) communication, other suitable communication, or acombination thereof. Communication between base station 300 andindividual monitors 200 may be bi-directional or uni-directional.Antenna 330 may be a high-gain antenna, and in some exemplaryembodiments base station 300 includes multiple (e.g., 2) such antennas330. In some exemplary embodiments, base station 300 includes an antennaconfigured to send and/or receive a positioning signal such as that of asatellite-based positioning system (e.g., GPS). Base station 300 canthen determine metrics from the received data. FIG. 8 depicts a diagramof an exemplary embodiment of monitoring system 100. As shown in FIG. 8,base station 300 includes a data reception module 302, a data processingmodule 304, a central synchronization (sync) module 310, a logic module312, a web server module 314, and a base station database 316.

As described above, base station 300 receives data from individualmonitors 200. Data reception module 302 of base station 300 may be incommunication with each active individual monitor 200. In some exemplaryembodiments data reception module 302 receives data from individualmonitors 200 via antenna 330 in communication with individual monitors200 through the RF link described above. Data reception module 302writes the received data to a data file, which may be, for example, acomma-separated values file or a tab delimited file. The file may be,for example, a single file used to write the data to, or a rolling file(file roll) based on, for example, time, number of entries, or size. Thedata file may be updated using any suitable interval and parameters. Forexample, 30 individual monitors 200 may be active and updating 5 datapoints at 2 Hz, in order to update the data file in near real time.

Data reception module 302 may perform a data integrity check on thereceived data. In some exemplary embodiments data reception module 302decrypts the received data. In some exemplary embodiments data receptionmodule 302 is agnostic to the received data, and does not decrypt thereceived data. In some exemplary embodiments data reception module 302buffers content as needed.

Data reception module 302 may include a data read module 332 that readsthe data from the data file and transmits it to data processing module304. Data read module 332 may run at any suitable interval, such as, forexample, 500 ms, to read the change in the data written to the datafile.

Prior to individual monitors 200 being used by individuals 10 during asession of athletic activity, each individual monitor 200 is connectedto base station 300 (e.g., by docking in docking port 318, orwirelessly) and is assigned an encryption key by data processing module304. Individual monitors 200 can use this encryption key to securelytransmit data to data reception module 304. Data processing module 304receives data from data reception module 302, as described above, andde-crypts the data, if encrypted, by using the unique encryption keyassigned to a particular individual monitor 200. Data processing module304 transmits the decrypted data to base station database 316, forstorage.

Base station database 316 is preferably configured for short termstorage of data generated during sessions of athletic activity, whilelong term storage is accomplished by web server system 500, as will bediscussed in greater detail below. Base station database 316 may includesufficient storage space for at least all data expected to be generatedin 1 session of the athletic activity. In some exemplary embodiments,base station database 316 includes sufficient storage space for at leastall data expected to be generated in 3 sessions of the athletic activity(e.g., greater than approximately 2 gigabytes). In some exemplaryembodiments, base station database 316 is configured for long termstorage, and includes sufficient storage space, for example, for atleast all data expected to be generated in 10 years of use monitoringathletic activities (e.g., greater than approximately 600 gigabytes).

Logic module 312 polls base station database 316 and applies algorithmsto the polled data to determine metrics and alerts. Logic module 312 candetermine a wide variety of metrics, including custom-designed metrics,by application of appropriate algorithms. Logic module 312 can transmitsuch metrics to web server module 314. More detailed description ofexemplary metrics and their use will be provided below.

In some exemplary embodiments, trainers 20 can create alerts forindividuals 10 in order to inform trainer 20 of the occurrence ofevents. Such alerts can be used to, for example, measure workouteffectiveness, manage training load, identify achievement of trainingtargets, or identify dangerous situations. Alerts can be based on anumber of metrics, such as, for example, distance (total and/or timewithin particular speed ranges), heart rate (present and/or cumulativetime within particular heart rate zones, heart rate moving outsideparticular heart rate zones), and power or training load. Such alertscan be generally applied to all individuals 10 (individually or ingroups), or can be tailored to be specific to a particular individual10. Such alerts can be generally applied to all sessions of athleticactivity, or can be tailored to be specific to a particular session ofathletic activity.

Trainers 20 can create such alerts via an administrative device, whichmay be a device such as, for example, group monitoring device 400 oranalysis device 600, described in greater detail below. In someexemplary embodiments, alerts can be created using a remote computer(e.g., by a team manager or medical support person) and can betransferred to the base station and to any of individual monitors 200,group monitoring devices 400, or analysis devices 600 (e.g., via theInternet, and/or any of the communications channels described herein).Trainers can create an alert by, for example, selecting a metric,selecting conditions (e.g., target metric value, time frame formaintaining target metric value, date range for achieving target, targetmetric range), specifying exceptions, assigning the alert to anindividual 10 (or a group of individuals 10), and associating the alertwith a session of athletic activity.

The created alert may be viewed in association with its associatedindividual 10 when viewing a dashboard (such as that displayed by groupmonitoring device 400 or analysis device 600, see FIGS. 16 and 20) ofassociated individual 10. Progress of individual 10 toward triggering analert (triggering occurs when the conditions of the alert are met) canbe monitored during a session of athletic activity via group monitoringdevice 400. Past alerts that have been triggered can be stored inassociation with individual 10 or a group of individuals 10, and thesealert histories may be viewed using, for example, group monitoringdevice 400 or analysis device 600. Examples of potential alerts includeexhibiting an irregular heart rate, exhibiting a body temperature above38 degrees C. (potentially a sign of hyperthermia), maintaining a heartrate of 85% of maximum or higher for 10 minutes or more, traveling adistance of 900 meters at a speed of 6.0 meters per second or more,achieving a training load of 700 Watt or more.

Logic module 312 can transmit information about such alerts (including,e.g., information indicating progress toward triggering an alert andinformation indicating an alert is triggered) to group monitoring device400 (via web server module 314 of base station 300) during athleticactivity of individual 10. The information about such alerts can bestored in base station database 316.

Web server module 314 can receive metric and alert information fromlogic module 312 for individual 10, or for multiple individuals 10(including groups of individuals 10). Web server module 314 can renderdisplay code (such as, for example, html5 (hypertext markup language 5)compliant code) based on a request from a client device such as, forexample, group monitoring device 400. In some embodiments, web servermodule 314 uses JavaScript® to open and maintain a web socket. Webserver module 314 can also serve a security function, by ensuring that arequesting client device is properly authenticated and that all data ispassed using https (hypertext transfer protocol secure). Web servermodule 314 may provide group monitoring device 400 with requestedmetrics and generated alerts during the athletic activity, via, forexample, an API layer.

Group monitoring device 400 can wirelessly receive metrics, alerts, andother information (e.g., identification information and attributes ofindividuals 10, or statistics relevant to individuals 10 or the athleticactivity generally) from base station 300. A single group monitoringdevice 400 may be in communication with base station 300, or multiplegroup monitoring devices 400 may be in communication with base station300 simultaneously. Group monitoring devices 400 may be portable withrespect to base station 300 and may communicate with base station 300via, for example, WLAN (wireless local area network), 2.4 GHz ISM(industrial, scientific, and medical) band, Bluetooth® (or Bluetooth LowEnergy (BTLE)), or cellular protocols.

In some exemplary embodiments, group monitoring device 400 includes amodule selection element 446 which allows selection of one or moreoperation modules to be displayed. The operation modules may beselectable using operation module icons. In some exemplary embodiments,selection of a plan module icon 464 may trigger display of a plan moduleincluding features designed to be used to plan a session of athleticactivity. In some exemplary embodiments, selection of a monitor moduleicon 466 may trigger display of a monitor module including featuresdesigned to be used to monitor a session of athletic activity in realtime during the session of athletic activity, as described furtherherein. In some exemplary embodiments, selection of an analyze moduleicon 468 may trigger display of an analyze module including featuresdesigned to be used to analyze a session of athletic activity in realtime during the session of athletic activity, or after completion of thesession of athletic activity, as described further herein. In someexemplary embodiments, selection of a report module icon 470 may triggerdisplay of a report module including features designed to be used todevelop reports (e.g., printable or displayable summaries of selectedinformation) related to a session of athletic activity.

In some exemplary embodiments, group monitoring device 400 includes adisplay 402 and an input 404, as shown, for example, in FIG. 9. In apreferred embodiment, group monitoring device 400 is a tabletcomputing-style device (such as a tablet personal computer or an iPad®,marketed by Apple Inc.®). Group monitoring device 400 may be, however,any other suitable device, such as, for example, a laptop computer, asmartphone, a personal computer, a mobile phone, an e-reader, a PDA(personal digital assistant), a smartphone, or other similar devicecapable of receiving and displaying information and receiving input.

In some exemplary embodiments, during a session of athletic activity,trainer 20 may use group monitoring device 400 to receive real timeinformation about individuals 10. This information may enable trainer 20to more easily accomplish a variety of goals. In the case that theathletic activity is a fitness exercise, trainer 20 can leverage realtime data received about the fatigue of particular individuals 10 orgroups of individuals 10 in order to, for example, inform data-drivenreal time decisions that optimize the performance of individuals 10 andreduce the potential for injury. For example, trainer 20 may modify acurrent session of athletic activity (e.g., shorten, extend, pause, end,or change the schedule of activity for the session) based on theinformation received from group monitoring device 400. Trainer 20 maymodify the session for particular individuals 10, or for groups ofindividuals 10. In the case that a present session of athletic activityhas been scheduled using a plan module of monitoring device 400 (asdescribed further herein), the planned schedule can be changed in realtime to correspond to decisions of trainer 20. Similarly, in the casethat the athletic activity is a competition (e.g., a soccer game),trainer 20 can leverage real time data received about the performance ofparticular individuals 10 or groups of individuals 10 in order to, forexample, inform data-driven real time decisions that optimize the chancefor success in the competition. In an exemplary embodiment, groupmonitoring device 400 can be used to monitor a single individual 10alone, as well as a group of individuals 10.

In some exemplary embodiments, group monitoring device 400 may be usedby broadcasters of an athletic activity in order to, for example,determine and relay to their audience information about individuals 10participating in the athletic activity.

Display 402 functions to display representations of individuals 10(including, for example, identification information, attributes,metrics, and alerts) during participation in a session of athleticactivity by individuals 10. The representations can take many forms,including, for example, charts (see FIGS. 13 and 14), dashboards (seeFIG. 16), graphs (see FIG. 15), maps (see FIG. 16), colors, symbols,text, images, and icons.

Input 404 is an interface that allows a user, such as trainer 20, tomanipulate the representations displayed by display 402. In a preferredembodiment input 404 is a touch-screen input. Input 404 may be, however,any other suitable input, such as, for example, a keyboard, avoice-recognition audio input, or push-button inputs. Input 404 mayfurther include a combination of various types of inputs. Input 404 maybe manipulated by trainer 20 to cause display 402 to show desiredrepresentations. The representations can update in real time during theathletic activity through the communication of group monitoring device400 with base station 300, which is in turn in communication withindividual monitors 200 worn by individuals 10 participating in theathletic activity, as described above.

In an exemplary embodiment, trainer 20 accesses group monitoring device400 by inputting unique login credentials via input 404. Alternatively,trainer 20 accesses group monitoring device 400 without inputting logincredentials. Upon accessing group monitoring device 400, trainer 20 maymanipulate input 404 to use group monitoring device 400 to monitorindividuals 10 in real time. Display 402 of group monitoring device 400can be fully customizable, and different persons using differentdisplays 402 may customize their displays differently. Multiplemonitoring devices 400 can be used simultaneously by multiple trainers20, and each can be customized independently from the others. Each ofmultiple monitoring devices 400 may monitor different individuals 10 orgroups thereof. Each of multiple monitoring devices 400 may monitorpresent different information and/or the same information in differentformats. Each of multiple monitoring devices 400 may be customized toinclude different alerts and/or markers (as discussed further herein).Such customizability may allow each of a group of trainers 20 to focuson and monitor different aspects of individuals 10 or groups thereof.Each display feature described herein can be modified and/or included ina particular view of display 402 at the option of a user of display 402(e.g., trainer 20). For ease of description, however, display 402 willbe presented herein as representing a variety of different “dashboards”,a dashboard being a visual representation of one or more elements. Insome exemplary embodiments, dashboards can be defined as default views,which can then be used or modified at the option of the user. Forexample, a team view dashboard may represent information relating toeach individual 10 on a team, as well as information relating to theteam as a whole, while an individual view dashboard may representinformation relating to a particular individual 10.

In an exemplary embodiment, display 402 of group monitoring device 400shows a team view dashboard (see, for example, the exemplary display 402of FIGS. 13, 17, 18, and 27-32, 33A, 33B, 34, and 35A-35D). The teamview dashboard may simultaneously display identification information andsummary metrics for all individuals 10 presently participating in themonitored athletic activity, or a group thereof. The identificationinformation may include individual name 406 and individual jersey number408, for example. In some embodiments, a photograph 410 of eachindividual 10 is also included as identification information (see, e.g.,FIGS. 27, 28, 31, 32, and 33A). The summary metrics shown in the teamview dashboard can be configured to be the metrics most applicable ormost beneficial to trainer 20. In the exemplary display 402 of FIG. 13,present heart rate, speed, training load, and power are shown for eachof Player A through Player H (Player A through Player H beingindividuals 10 presently participating in the monitored athleticactivity). The metrics shown in FIG. 13 are shown as numerical values.Display of metrics is not limited to display of numerical values,however. Metrics may be represented in other suitable ways as would beappreciated by one of skill in the art, such as, for example,graphically (see, e.g., FIG. 15), or in map form (see, e.g., FIGS. 16and 17).

In some exemplary embodiments, for example, display 402 of FIG. 27,heart rate, power, distance, and efficiency are shown for each of PlayerA through Player L, with these values for additional players availableto be viewed by scrolling down past Player L. Also shown for each ofPlayer A through Player L are fields for alerts and notes. In someexemplary embodiments, as depicted in, for example, FIGS. 27 and 31,note icons 425 and alert icons 432 may indicate the presence of notes oralerts. Selection of such note icons 425 and alert icons 432 may triggerdisplay of additional information related to an associated mote or icon.For example, the team view dashboard of FIG. 27 indicates that player Ahas 1 alert, Player E has 3 alerts, and Player L has 2 alerts, and thateach of Players A, D, E, I, and K have notes associated with theirentries. Such notes and alerts are described in greater detail herein.

In some exemplary embodiments, display 402 displays a subset of allmonitored individuals 10. In this way trainer 20 can focus on particularindividuals 10. In some exemplary embodiments, the subset of individuals10 displayed can be defined by trainer 20, and display 402 can include aselection feature, for example, selection feature 428 of FIGS. 28 and29, that allows trainer 20 to select to include or not includeparticular individuals 10 in the viewable subset.

Additionally or alternatively, the team view dashboard may show groupsummary metrics for groups of individuals 10 participating in themonitored athletic activity. The group summary metrics may be averagesof the corresponding metrics for each individual 10 belonging to thegroup, or the group summary metrics may be calculated using anindependent algorithm designed to reflect a desired attribute of thegroup as a whole. In the exemplary display 402 of FIG. 13, presentaverage heart rate, speed, training load, and power are shown for theteam (i.e., Player A through Player H), and for a group including asub-set of the team (i.e., Player A, Player C, and Player E). The valuesfor heart rate, speed, training load, and power may update in real timeduring the athletic activity so as to reflect present values.

Team view dashboard is not limited to display of heart rate, speed,training load, and power, and is not limited to the display of 4metrics. Team view dashboard can be customized to display those metricsmost applicable or most beneficial to trainer 20, and may display, forexample 3 to 5 distinct metrics for each individual 10. In someexemplary embodiments the metrics displayed can be set prior to theathletic activity during a setup procedure. In some exemplaryembodiments the metrics displayed can be changed during the athleticactivity by manipulation of input 404.

A particular metric of the displayed metrics in team dashboard view maybe designated as a featured metric 414, which may be displayed withemphasis relative to other metrics. A featured metric may beindependently designated (e.g., by trainer 20) for an individual 10, orfor a group of individuals 10. Featured metric 414 may be displayed moreprominently or in greater detail than other metrics, in order to allowtrainer 20 to easily get an at-a-glance view of the featured metricacross all individuals 10 participating in the athletic activity. Insome exemplary embodiments featured metric 414 may be changed duringmonitoring of the athletic activity to any available metric, byappropriate manipulation of input 404 (e.g., selecting the metricdesired to be featured, such as by selecting one of featured metricoptions 430 shown in, for example, FIG. 30). In some exemplaryembodiments trainer 20 can toggle back and forth between featured metricviews.

Featured metric 414 may be featured in a variety of ways. For example,it may be displayed in a color (or with a background color) differentfrom that of the other displayed metrics, it may be displayed largerthan the other metrics, it may flash or blink, it may include a largerbackground area than that of other metrics, it may be positioned closestto the identification information of individuals 10, it may include astatus bar, chart, or graph (e.g., status bar 462), or it may exhibit acombination of these or other characteristics. In the exemplary display402 of FIG. 13, heart rate is featured by including a larger backgroundarea than that of the other metrics and by being positioned closest tothe identification information of individuals 10. In the exemplarydisplay 402 of FIG. 27, power is featured by including a status bar nextto the power entry for each individual 10. In the exemplary display ofFIGS. 30 and 32, power is further featured by additionally displaying avalue representing power larger than other values. In the exemplarydisplay 402 of FIG. 31, heart rate is featured by including a status barand by presenting a value representing heart rate larger than othervalues.

Some exemplary embodiments may, if alerts have been established for ametric of an individual 10, include an indication of whether a value ofthe metric is within particular zones relative to the alert parameters.For example, a color of the background area of the metric may change, oran icon may appear, based on, for example, whether the value is withinor outside the zone, or on the proximity of the value to a threshold. Inan exemplary embodiment where an alert is established for maintaining aheart rate of 85% of maximum or higher for 10 minutes or more, when avalue of the heart rate of individual 10 is at 85% of maximum or higher,the background of the area containing the heart rate value of individual10 is green, and when the heart rate has been at 85% of maximum orhigher for 10 minutes or more, a star icon appears in the areacontaining the heart rate value of individual 10, and an audio sound isplayed by a speaker of group monitoring device 400. In some exemplaryembodiments, as shown in, for example, FIGS. 31-33A, an indication thatan alert has been triggered can be provided by a change in color of thearea around the name of an associated individual 10, and a circle orother alert icon 432 representing the alert can be presented indicatingthe presence and/or number of alerts that are associated with theindividual 10. The change in color may be maintained as long as an alertis active, or may change at the triggering of the alert, and fade orchange back to its original color after a period of time. In someexemplary embodiments, individual monitors 200 can provide indication ofan alert to an associated individual 10 via, for example, emitting anaudible noise, vibrating, or providing a visual indication (e.g., via anLED or LCD display).

In some exemplary embodiments, if an alert is triggered, trainer 20 canselect a representation of the alert to thereby access more informationabout the alert, as shown in, for example, FIGS. 33A and 34. In someexemplary embodiments, selecting the representation of the alert leadsto a detailed chart view of the metric that triggered the alert. In someexemplary embodiments, display 402 may display all active alerts, at apoint or period in time, for all monitored individuals 10 or subsetsthereof. In some exemplary embodiments, new alerts can be indicated by,for example, a flashing icon or a temporary pop-up box 434 showinginformation relating to the new alert, as is shown in the exemplaryembodiments of FIGS. 33A, 33B, 34, and 35A-35D, for example.

In some exemplary embodiments, pop-up box 434 includes information abouta single alert (e.g., FIG. 33A). In some exemplary embodiments, pop-upbox 434 includes information about multiple alerts (e.g., FIG. 33B). Themultiple alerts can be displayed according to any suitable criteria, forexample, the multiple alerts may be active alerts related to aparticular individual 10 or group of individuals 10, or may be alertstriggered within some time period prior to the present time. In someexemplary embodiments, pop-up box 434 indicates the presence and/ornumber of alerts triggered. This number may include, for example, allactive alerts, all unviewed alerts, or the number of alerts triggeredwithin some time period prior to the present time (e.g., FIG. 35C). Insome exemplary embodiments, a pop-up box 434 indicating the number ofalerts triggered appears in the place of a pop-up box 434 includingadditional alert information when the number of alerts to be displayedis above some threshold number.

In some exemplary embodiments, an alert management window 438 can bedisplayed in response to selection of an alert management icon 448, asdepicted in, for example, FIG. 35D. Alert management window 438 mayinclude information about all active alerts or a subset thereof, and mayallow dismissal or acknowledgement of such alerts.

In some exemplary embodiments, the team view dashboard is sortable inreal time. Trainer 20 may manipulate input 404 so as to cause display402 to show information for individuals 10 sorted by a desired metric.For example, trainer 20 may select a displayed heart rate metric (by,for example, selecting the metric label or a sort icon associated withthe metric), and the information for individuals 10 may be rearranged soas to be represented in ascending or descending order. For example, FIG.19 shows individuals 10 rearranged from the individual 10 with thelowest heart rate to the individual 10 with the highest heart rate.Further selections of the heart rate metric may cause the informationfor individuals 10 to change from ascending to descendingrepresentations, and vice versa. In some exemplary embodiments, trainer20 may similarly sort by, for example, name 406, position in space(e.g., location on the field or court), position on team (e.g.,goalkeeper, defender, point guard), jersey number 408, physiologicalstatus, connection status, or active alerts. Such features can allowtrainer 20 to easily see which individuals 10 have high and low metricsrelative to other individuals 10.

In some exemplary embodiments, the team view dashboard is filterable inreal time. Trainer 20 may manipulate input 404 so as to cause display402 to show information for a subset of individuals 10. For example,trainer 20 may select one or more groups representing a subset ofindividuals 10. Groups can be selected in a variety of ways. In someexemplary embodiments trainer 20 selects a group label or a filter iconassociated with the group. In some exemplary embodiments trainer 20selects individuals to create a group in real time. In some exemplaryembodiments trainer 20 inputs information used to identify members of agroup, such as, for example, all individuals 10 having higher than aparticular a heart rate, all individuals 10 having higher than aparticular training load percentage, all individuals assigned aparticular position, or all individuals having a particularphysiological status. When a group is selected the display may changesuch that information for only those individuals 10 that are included inthe group is displayed. Such features can allow trainer 20 to easilyfocus on the metrics associated with a group of individuals 10.

In some exemplary embodiments, the team view dashboard can also be usedto monitor the status of connection of individual monitors 200 to basestation 300. If, for example, an individual 10 travels out of range ofbase station 300, base station 300 may not receive normal transmissionsfrom the individual monitor 200 of that individual 10. The team viewdashboard can indicate that no data is being received by base station300 for that individual 10 by, for example, graying out theidentification information of that individual 10 (see, e.g., Player G ofFIGS. 27, 31, 32, and 34), by including a strikethrough throughinformation relating to that individual 10, or by including an icon inassociation with the identification information of that individual 10.

In some exemplary embodiments, alternative representations can replacethe above-described representation of FIG. 13, or can be used asselectable alternative views, allowing trainer 20 to choose between theabove-described representation and the alternative representations. Thealternative representations of FIGS. 17 and 18 include multiple panels,each showing information for a particular individual 10. FIG. 17includes a location component 412 showing the present location ofindividuals 10 on playing field 30, where individuals 10 are depictedrepresented by their identifying numbers. In some exemplary embodiments,as depicted in, for example, FIG. 60, individuals 10 are represented bytheir photographs. FIG. 18 includes a featured metric 414 (heart rate)displayed prominently in the center of each panel, as well as a key 416showing what metric the values in each panel represent. Trainer 20 mayselect a metric on key 416 to have it displayed as the featured metric414. FIG. 18 also includes a list of individuals 10 not activelymonitored. Trainer 20 may select an individual 10 from this list toactively monitor that individual. Operation of the alternativerepresentations of FIGS. 17 and 18 is similar to operation of theabove-described representation of FIG. 13.

In some exemplary embodiments, location component 412 shows the presentlocation of individuals 10 on the playing field, and selection of arepresentation of one of individuals 10 triggers display of a status boxdisplaying information about the current status of the selectedindividual 10. In some exemplary embodiments, as depicted in, forexample, FIG. 60, location component 412 may include a heat map 413,providing a visual indication of concentrations of individuals 10 inareas of the playing field, which information may help trainer 20determine whether to redistribute individuals 10. Such visual indicationmay include coloring areas of higher concentration of individuals 10differently from areas of lower concentrations of individuals 10.Location component 412 can be used to monitor individuals 10 in realtime, or can be used to review the locations of individuals 10 from apast session of athletic activity or earlier in the present session ofathletic activity.

In an exemplary embodiment, display 402 of group monitoring device 400shows an individual view dashboard (see, for example, the exemplarydisplays 402 of FIGS. 16 and 36A, 36B, 37A, 37B, and 38-41). Trainer 20may access an individual view dashboard by, for example, selecting anindividual 10 on the team view dashboard. The individual view dashboardmay show information about the selected individual 10, such as, forexample, biographical information (e.g., photograph 410, name 406,jersey number 408, position), attributes (e.g., height, weight), metrics(e.g., time active, heart rate, speed, distance traveled, intensitylevel, training load, efficiency, location), statistics (e.g., pointsscored), alerts, notes, and condition (e.g., active, healthy,rehabilitation). In some exemplary embodiments the individual viewdashboard shows different information about the selected individual 10than that shown in the embodiment of FIG. 16.

In some exemplary embodiments, when trainer 20 selects an informationentry, a detailed view of that information may be displayed. Forexample, if trainer 20 selects ‘heart rate’ on the individual viewdashboard for Player A shown in FIG. 16, display 402 may display adetailed chart and/or graph 418 showing a history of Player A's heartrate throughout the present athletic activity (see, e.g., FIG. 20). Insome exemplary embodiments, trainer 20 may select a ‘power’ indicator onthe individual view dashboard, and display 402 may display a detailedchart and/or graph 418 showing a history of the selected player's power(see, e.g., FIG. 36A).

In some exemplary embodiments, any applicable alert information (e.g.,training zones, thresholds) specific to the selected metric for selectedindividual 10 is displayed in the detailed view. For example, as shownin the detailed views of FIGS. 20 and 36A, training zones 420 for PlayerA's heart rate are overlaid on graph 418 of Player A's heart rate. Insome exemplary embodiments, areas of zones 420 may be highlighted wherecoincident with data of graph 418, as depicted in, for example, FIG.36B. Also, for example, as shown in the detailed view of FIG. 36A,training zones 420 (e.g., for a player's speed) may be displayed in apie chart 472. In some exemplary embodiments, alerts relevant to aparticular metric may be indicated by an icon displayed in associationwith the chart and/or graph indicative of that metric. For example, inthe detailed view of FIG. 39, an alert icon 432 indicates an alertassociated with the player's heart rate, and an alert icon 432 indicates3 alerts associated generally with the player.

Selection of these alerts may trigger presentation of more detailedinformation about the alert, for example, in the form of a pop-upgraphic 434, as shown in FIG. 40. In some exemplary embodiments, trainer20 can select multiple information entries and display 402 canincorporate information regarding the selected multiple informationentries in the detailed view. For example, FIG. 20 shows Player A'sspeed shown in graph 418 of display 402. In some exemplary embodiments,display 402 may display additional detailed charts and/or graphs 436while displaying the primary chart and/or graph 418. In some exemplaryembodiments, the additional detailed charts and/or graphs 436 aredisplayed less prominently (e.g., smaller) than the primary chart and/orgraph 418, as depicted in, for example, FIGS. 36A and 39. In someexemplary embodiments, if an area on chart and/or graph 418 is selected(e.g., by trainer 20), more detailed information about the displayedmetric may be displayed. For example, selecting near a particular pointon a line graph may trigger display of a graphic 474 indicating thevalue of one or more metrics at that point (see, e.g., FIGS. 37B and38). In some exemplary embodiments, chart and/or graph 418 may includeinformation indicative of more than one metric. For example, chartand/or graph 418 may include power and heart rate on the same chartand/or graph (see, e.g., FIGS. 37A and 37B).

In some exemplary embodiments, chart and/or graph 418 may include metricinformation for past sessions of athletic activity, which may be storedwithin group monitoring device 400 or transmitted thereto by, forexample, base station 300. In some exemplary embodiments, chart and/orgraph 418 may include information indicative of more than one timeperiod for one or more metrics. For example, chart and/or graph 418 mayinclude heart rate information for the present or most recent session ofathletic activity separate from or overlaid with heart rate informationfor one or more prior sessions of athletic activity on the same chartand/or graph.

In some exemplary embodiments, trainer 20 may input notes about aparticular individual 10, group of individuals 10, or team, by, forexample, selecting a note field 422 of the individual view dashboard, asshown in, for example, FIGS. 16 and 41. In some exemplary embodiments,note field 422 may indicate the presence of notes, display notes, and/orprovide an option or input to create new notes. In some exemplaryembodiments, selection of note field 422, or otherwise accessing noteadding capability, may cause display 402 to display a create note window438 where trainer 20 can input a note, as shown in, for example, FIG.44.

Selecting note field 422 may cause a free-text note entry field toappear, into which trainer 20 can enter text. In some embodiments,selecting note field 422 causes a microphone in group monitoring device400 to activate and record voice input of trainer 20, allowing trainer20 to record a voice note. Trainer 20 may input desired information innote field 422, such as, for example, a reminder to closely monitor theheart rate of individual 10, a reminder that individual 10 appearsdehydrated, a determination that individual 10 should be congratulatedfor a good play, or a determination that the team should practice aparticular play. In some exemplary embodiments, notes include timeinformation, indicating, for example, the time to which a note pertains,or the time a note was created or modified, which can be useful for alater correlation between recorded data and the notes. Such timeinformation may be entered manually or determined automatically.

In some exemplary embodiments, trainer 20 may select markers 440 toinclude in a session timeline 424. Such markers 440 may be selectedbefore (e.g., using a plan module, as described further herein), during,or after the athletic activity. Session timeline 424 may keep track ofthe time elapsed or remaining in a session of athletic activity, or in asubset or interval of the session of athletic activity, and may berepresented by, for example, numerical values (e.g., numerical value450) or a moving point on a line representing total session time, asshown in, for example, FIGS. 13, 16, 19, 20, and 27-44. A marker 440 maybe used to identify events within a training session. A trainer 20 mayselect a marker 440 by, for example, selecting an add marker button 426(see, e.g., FIGS. 13, 16, 20, and 42A), or by selecting a point onsession timeline 424, for example.

In some exemplary embodiments, selection of add marker button 426 causesdisplay 402 to display an add marker window 442, allowing input ofparameters to define the marker, as shown in, for example, FIGS. 42E and43. Add marker window 442 may include a note input area 444 wheretrainer 20 can input a note associated with a marker 440. A marker 440may be associated with a team as a whole, with sub-groups of individuals10, or with a particular individual 10. When selecting a marker 440,trainer 20 may designate the marker type, which can be, for example, an“activity start” marker to designate the point at which an activitystarts, an “activity stop” marker to designate the point at which anactivity stops, or a “flag marker” to designate the point at which aparticular event occurs. For activity-based markers, marker attributesmay include the type of activity (e.g., cardio, drill, strength,recovery, other) and the activity name, for example. For flag-basedmarkers, marker attributes may include the type of flag (e.g., injury,rest, off field, out of range).

In some exemplary embodiments, markers 440 include time information,indicating, for example, the time to which a marker 440 pertains, or thetime a marker 440 was created and/or modified, which can be useful for alater correlation between recorded data and the markers. Such timeinformation may be entered manually or determined automatically. In someexemplary embodiments, trainer 20 can input notes to be associated withthe marker, or with a particular point on session timeline 424. In someexemplary embodiments, as depicted in, for example, FIGS. 27 and 31,note icons 425 positioned at points on session timeline 424 canrepresent such notes. Attributes of markers 440 may be designated bytrainer in real time, or can be pre-defined. Markers 440 can beassociated with session timeline 424 at the time they are created, orcan be associated with any other time on session timeline 424. Markerscan be useful to trainer 20 in analyzing the performance of individuals10 during the athletic activity as well as after the athletic activity,by associating contextual information with particular times andindividuals. In some exemplary embodiments, if a part of a session ismarked with activity markers, past data from the same types ofactivities of an individual 10 can be retrieved and overlaid with morerecent (including presently generated) data of the individual 10,thereby facilitating comparison of data for an individual 10. Markers440 and their use, as described herein, can apply to a particularindividual 10, or to groups of individuals 10 (e.g., one or more teamsor leagues of individuals 10, or one or more sub-groups of one or moreteams or leagues of individuals 10).

In some exemplary embodiments, analysis markers 440 can be defined andmanipulated by a user (e.g., trainer 20). Analysis markers 440 can beused as boundaries to define a subset of metric information as afunction of an interval parameter. Group monitoring device 400 may thendisplay metric information (e.g., performance metric information, suchas, for example, heart rate) corresponding only to the subset of metricinformation defined by analysis markers 440. Analysis markers 440 can bedefined for a particular individual 10, or for a group of individuals10. An interval parameter may be any parameter that can have adesignated first point and second point, which can be designated by, forexample, a first analysis marker 440 and a second analysis marker 440,thereby defining an interval therebetween suitable to measureperformance. For example, the interval parameter may be time ordistance.

In some exemplary embodiments, analysis markers 440 define a portion ofthe athletic activity engaged in by individuals 10. The portion ofathletic activity may be, for example, warmup, a drill, live play, cooldown, a line drill, sprints, repeated sprints, a conditioning drill, astrength training drill, a tactical drill, or a skills drill for aparticular sport. For example, if a conditioning drill begins 10 minutesinto an athletic activity, and ends 15 minutes into the athleticactivity, a first analysis marker 440 may designate a time 10 minutesinto the athletic activity, and a second analysis marker 440 maydesignate a time 15 minutes into the athletic activity, thereby defininga 5 minute interval therebetween, corresponding to the conditioningdrill.

In some exemplary embodiments, analysis markers 440 may be defined basedon past metric information, by manipulating input 404 after the sessionof athletic activity (e.g., defining an interval in the past). In someexemplary embodiments, analysis markers 440 may be defined based onpresent metric information, by manipulating input 404 during the sessionof athletic activity (e.g., defining a beginning point in real timeduring the athletic activity, and then an ending point in real time). Insome exemplary embodiments, analysis markers 440 may be defined based onexpected future metric information or expected activity, by manipulatinginput 404 before the session of athletic activity (e.g., definingexpected beginning and ending points in time during a planned session ofathletic activity).

When defined based on expected future metric information, groupmonitoring device 400 can be used to coordinate the planned session ofathletic activity, by scheduling intervals of particular athleticactivity. For example, analysis markers 440 may define a conditioningdrill to take place in the first 5 minutes of athletic activity, astrength training drill in the following 5 minutes, and a skills drillin the following 5 minutes. Group monitoring device 400 may indicate totrainer 20 when an interval is scheduled to begin and end, and when atransition between intervals is scheduled to take place, and trainer 20may communicate this information to individuals 10. In some exemplaryembodiments, base station 300 may send a signal to individual monitors200 indicating the transition between intervals, or the beginning or endof a particular interval, and individual monitors 200 may communicatethis information to individuals 10 via, for example, emitting an audiblenoise, vibrating, or providing a visual indication (e.g., via an LED orLCD display). In this way, individuals 10 can be alerted as to the startor end of a portion of athletic activity corresponding to a definedinterval.

In some exemplary embodiments, to facilitate planning a session ofathletic activity, display 402 may display a plan module, which mayinclude utilities useable to plan the session of athletic activity, asdepicted in, for example, FIGS. 45-51. Display 402 may include sessionduration 482, which may be manipulated by a user to define the durationof a session of athletic activity. Display 402 may display a sessiontimeline 424, which may indicate a timeline for a planned session ofathletic activity. Trainer 20 may select points and portions of sessiontimeline 424 in order to define intervals of athletic activity scheduledat the selected times. Such intervals of athletic activity may bescheduled for an entire team of individuals 10, for other groups ofindividuals 10, or for single individuals 10. In an exemplaryembodiment, depicted, for example, in FIG. 45, intervals of athleticactivity are scheduled for groups of individuals 10, and these groupsare displayed with their own timelines 478. In some exemplaryembodiments, timelines 478 are aligned with session timeline 424 suchthat, upon selection of a point on session timeline 424, or uponoccurrence of a time corresponding to the point, a line or otherindicator 494 extends to corresponding points on timelines 478, asdepicted in, for example, FIG. 46.

Various parameters can be defined in association with a planned sessionof athletic activity and/or the intervals thereof, including, forexample, markers, training targets and alerts, as well as intensitylevels. In some exemplary embodiments, such parameters can be defined byselection using options and/or menus 480, as depicted in, for example,FIGS. 45-47, selection of which may trigger display of a training targetand alert window 486, as depicted in, for example, FIG. 49. Trainingtarget and alert window 486 may allow selection of a metric (e.g., heartrate, power, speed), and definition of training or alert zones relativeto a percentage of a maximum value for the metric. Training target andalert window 486 may also allow for definition of training or alertzones bounded by definite values of the metric. In some exemplaryembodiments, markers 440 defined in association with a planned sessionof athletic activity may be displayed on session timeline 424 during thesession of athletic activity, as depicted in, for example, FIG. 42E.Display 402 may be configured to allow modification, addition, ordeletion of such markers 440 by trainer 20 during the session ofathletic activity.

In some exemplary embodiments, such parameters (e.g., markers, trainingtargets, alerts, intensity levels) can be defined by selection of apoint on timeline 478, as depicted in, for example, FIG. 47. In someexemplary embodiments, such selection of a point on timeline 478 maytrigger display of options and/or menus 481 for input of markers,training targets, alerts, and/or intensity levels associated with apoint in time or interval corresponding to the selected point. In someexemplary embodiments, such selection of a point on timeline 478 maytrigger a window for input of an alert or marker associated with thepoint in time or interval corresponding to the selected point.

In some exemplary embodiments, as depicted in, for example, FIG. 48,display 402 displays an edit activity window 484, which includes optionsand inputs facilitating defining of various aspects of an activityassociated with an interval of a session of athletic activity. Variousactivities (e.g., drills, games, tests, training components) may bestored in a database (e.g., base station database 316, or a memoryincluded in group monitoring device 400). Edit activity window 484 mayallow a user to search for an activity by choosing a training component(e.g., warm up, drills, competition), choosing an intensity level (e.g.,low, medium, high), and choosing the number of players involved. Editactivity window 484 may provide results showing activities matching theinput search criteria. Edit activity window 484 may provide an option toassign the resultant activities to individuals 10 or groups thereof, andto choose coaches or trainers 20 to manage the assigned activities. Editactivity window may also allow association of such an activity with atime and duration, thereby scheduling an interval of the session ofathletic activity. Such activities may be designated by markers 440,which may be displayed on session timeline 424 during the session ofathletic activity, as depicted in, for example, FIG. 42E. Suchactivities may be designated prior to a session of athletic activity(e.g., using a plan module of group monitoring device 400), during asession of athletic activity, or after a session of athletic activity.

In some exemplary embodiments, as depicted in, for example, FIG. 50,display 402 may display a calendar 488 representing sessions of athleticactivity and intervals thereof that are scheduled for a set time period(e.g., one week, one month, five days, one day). The displayed timeperiod may be defined by a user. Display 402 may display sessions ofathletic activity and intervals thereof scheduled for the past, present,and/or future. In some exemplary embodiments, the types of sessions ofathletic activity and intervals thereof displayed may be filteredaccording to criteria input or selected by a user.

In some exemplary embodiments, as depicted in, for example, FIG. 51,selection of a particular time period displayed in calendar 488 (e.g., aparticular day), may trigger display of a detailed view of scheduledevents for the selected time period. For example, a detailed schedulewindow 490 may display an overall session of athletic activity scheduledfor the selected time period, as well as intervals of the session ofathletic activity and their characteristics (e.g., type of interval,applicability of interval to particular groups or individuals 10,beginning and end times of interval, description of activities to beperformed during interval, location of interval).

In some exemplary embodiments, as depicted in, for example, FIG. 52,display 402 displays a session list 492, which may depict a list ofscheduled sessions of athletic activity, as well as intervals ofathletic activity associated therewith. Session list 492 may displaysessions of athletic activity scheduled for times that have passed,scheduled for the present (e.g., the present time or day), and scheduledfor the future.

In some exemplary embodiments, display 402 may display a session controlmonitor 452, which may provide information relating to a past, ongoing,or future session of athletic activity, as depicted in, for example,FIGS. 42A and 42B. When used during a session of athletic activity,session control monitor 452 may help trainer 20 facilitate the session,by, in addition to providing information about individuals 10, byproviding a session information feature 454, as depicted in, forexample, FIGS. 42A and 42F. Session information feature 454 may provideinformation about, for example, a present interval of athletic activity.In some exemplary embodiments, session information feature 454 mayinclude a diagram 456 depicting intended movement of individuals 10during, for example, a particular play or other strategic action. Insome exemplary embodiments, session information feature 454 may includedescription 458 of, for example, a particular play or other strategicaction. In some exemplary embodiments, session information feature 454may include a schedule 460 of, for example, past and/or upcomingintervals of athletic activity.

In some exemplary embodiments, selection of an entry in schedule 460 maytrigger display of a session information feature 454 related to thatentry, as depicted in, for example, FIG. 42F. Session timeline 424 mayinclude information displayed in schedule 460, such that selection of apoint on session timeline may trigger display of information relevant tothat point in the session (e.g., time selected, interval of athleticactivity scheduled for time selected). Such information may be displayedin, for example, a timeline information window 476, as depicted in, forexample, FIGS. 42C and 42D. This information can be useful to trainer 20to facilitate an ongoing session of athletic activity, and can bedefined in advance of the session of athletic activity. In someexemplary embodiments, information in session information feature 454can be defined after, and applied to, a past session of athleticactivity, and can be used, for example, to help trainer 20 analyze thepast session.

In some exemplary embodiments, as depicted in, for example, FIG. 54,display 402 includes a status icon 496 that, when selected, triggersdisplay of a status menu 498. Status menu 498 may display informationabout the statuses of various components of group monitoring system 100.Status menu 498 may include information about, for example, the batterylife remaining in group monitoring device 400 or base station 300, theconnectivity and/or signal strength between group monitoring device 400and base station 300, the connectivity and/or signal strength betweengroup monitoring device 400 and the Internet or other network, and thenumber of individuals connected to base station 300.

Exemplary embodiments of the present invention may include data flowssuch as that shown in FIG. 12, which depicts a data flow including areal-time monitoring flow 950, a post-session data integrity flow 960,and a post-session analysis flow 970. At box 902 of FIG. 12, dataprocessing module 304 of base station 300 assigns encryption keys toeach individual monitor 200 (also referred to as a “player pod”), andeach individual monitor 200 is connected to sensors 202. At box 904,sensors 202 determine raw data indicative of characteristics of amonitored individual 10 (data indicative of, e.g., physiologicalcharacteristics, performance characteristics, position characteristics,and/or orientation characteristics). At box 906, sensors 202 send theraw data to individual monitor 200 via a wired or wireless connection.At box 908, individual monitor 200 transmits the data to data receptionmodule 302 of base station 300 via a wireless connection, in real time.At box 942, cameras (e.g., camera monitoring system 700, video feedcamera 804) determine image data. At box 944, the cameras send the imagedata to data reception module 302 of base station 300.

At box 910, data reception module 302 of base station 300 writes thedata to a file. At box 912, data reception module 302 of base station300 sends the file to data processing module 304 of base station 300. Atbox 914, data processing module 304 of base station 300 validates anddecrypts the data. At box 916, data processing module 304 of basestation 300 stores the decrypted data in base station database 316. Atbox 918, logic module 312 of base station 300 accesses the decrypteddata and, using algorithms, determines metrics and alerts. At box 920,logic module 312 of base station 300 sends the metrics to web server 314of base station 300. At box 922, web server 314 of base station 300sends the metrics to live monitoring devices 400.

At box 924, logic module 312 of base station 300 stores the metrics andalerts in base station database 316. At box 926 individual monitors 200are connected to base station 300 via a wired connection and upload datato data reception module 302 of base station 300. At box 928, datareception module 302 of base station 300 writes the data to a file. Atbox 930, data reception module 302 of base station 300 sends the file todata processing module 304 of base station 300. At box 932, dataprocessing module 304 of base station 300 validates and decrypts thedata. At box 934, data processing module 304 of base station 300performs data filtering (e.g., data de-duplication) if necessary, andstores the decrypted data in base station database 316. At box 936,central sync module 310 of base station 300 accesses and sends decrypteddata, metrics, and alerts (“session data”) to web server system 500. Atbox 930, web server system 500 stores the session data in web serverdatabase 502 of web server system 500. At box 940, web server system 500sends the session data to analysis devices 600.

Group monitoring system 100 can include any suitable number ofcomponents such as individual monitors 200, base stations 300, groupmonitoring devices 400, or analysis devices 600. In an exemplaryembodiment, group monitoring system includes 30 individual monitors 200,1 base station 300, and 2 group monitoring devices 400.

After completion of a session of athletic activity, individuals 10 maydock their individual monitors 200 in one of docking ports 318 of basestation 300. When docked with docking port 318, batteries 212 ofindividual monitors 200 can be charged, and data can be transferred fromindividual monitors 200 to base station 300. As noted above, individualmonitors 200 store sensed data and also transfer sensed data wirelesslyto base station 300 during an athletic activity. In order to mostefficiently use bandwidth, data may be transferred wirelessly during theathletic activity at a lower resolution than it is sensed and stored inindividual monitors 200. Due to communication errors, some data may notbe transmitted successfully from individual monitors 200 to base station300 (e.g., if an individual moves out of range of base station 300).Thus, the data stored in individual monitors 200 at the conclusion of asession of athletic activity may be more complete or accurate than thedata stored in base station database 316.

In some exemplary embodiments, data can be transferred from individualmonitor 200 to base station 300 at full resolution (i.e., raw data) andstored in base station database 316 (and/or web server database 502,once transferred thereto) at full resolution as well. Storing such rawdata for each individual 10 for each session may be useful forsubsequent data analysis, for example to perform recalculations, ofmetrics or calculations of new and different metrics using new anddifferent algorithms.

In some exemplary embodiments, data and metrics can be stored in ageneral database (e.g., a database shared by several of the systemsdescribed herein, or a general sports database for individuals).

While docked in docking ports 318 of base station 300, individualmonitors 200 can directly transmit their stored data to data processingmodule 304 (via data reception module 302). Data processing module 304can then filter the data received from individual monitors (e.g., dataprocessing module 304 can perform a de-duplication process on the datato avoid storing duplicate data in base station database 316) and storethe data in base station database 316.

In some exemplary embodiments, base station 300 includes a central syncmodule 310. Central sync module 310 of base station 300 can communicatethrough an Internet connection with a web server system 500, web serversystem 500 being external to base station 300. If base station 300 isconnected to the Internet via an Ethernet (or other wired) connection,such communication can take place over the Ethernet (or other wired)connection. If base station 300 is not connected to the Internet via anEthernet (or other wired) connection, communication can take placewirelessly, for example over a cellular network (e.g., GSM broad band2.5G or 3G). Central sync module 310 includes data upload and downloadcapabilities for uploading session data about a monitored athleticactivity, or diagnostic information about base station 300 and othercomponents, and to download user data such as, for example, updatedfirmware to be installed in individual monitors 200 via docking port240, or updated software for use in base station 300. Central syncmodule 310 can upload data stored in base station database 316 to webserver system 500. Such data may include data, metrics, and alertsgenerated during the athletic activity. When receiving such data, webserver system may store it in a web server database 502.

Web server system 500 can render display code (such as, for example,html5 compliant code) based on a request from a client device such as,for example, analysis device 600. Web server system 500 can also serve asecurity function, by ensuring that a requesting client device isproperly authenticated and that all data is passed using hUps. Webserver system 50 u may provide analysis device 600 with requestedmetrics and generated alerts stored in web server database 502, via, forexample, an API layer.

Analysis device 600 is depicted in FIG. 10 and includes a display 502and an input 504. In an exemplary embodiment, analysis device 600 is atablet computing-style device (such as a tablet personal computer or aniPad®, marketed by Apple Inc.®). Analysis device 600 may be, however,any other suitable device, such as, for example, a laptop computer, asmartphone, or a personal computer. Analysis device 600 can access datain web server database 502 and display the information to a user ofanalysis device 600 (e.g., trainer 20). Although analysis device 600 andgroup monitoring device 400 are described separately herein, in someexemplary embodiments, group monitoring device 400 and analysis device600 are the same device.

In some exemplary embodiments, analysis device 600 can be located at aremote location with respect to base station 300 or the relevantathletic activity, and can be used to access and display data andmetrics in real time. In such an embodiment, base station 300 cantransfer the data and metrics to web server 500 in real time, so thatthe data and metrics can be accessed for display by analysis device 600,as described above. Such an embodiment may be useful for a user tomonitor an ongoing session of athletic activity from a remote location(e.g., a trainer 20 that could not be present at a match, or a teamowner that desires to monitor a training session without physicallyattending the session).

After completion of a session of athletic activity, a trainer 20 may useanalysis device 600 to review and analyze information about individuals10, including information about past performances of individuals 10during past sessions of athletic activity. Depending on the number ofpast sessions of athletic activity for which data is available in webserver database 502, post-session analysis of an individual 10 usinganalysis device 600 may provide trainer 20 with information spanning alonger period than the information provided during an athletic activityby group monitoring device 400. Trainer 20 may access and view the datausing analysis device 600, however, in much the same way as has beendescribed above with respect to group monitoring device 400. Forexample, analysis device 600 may be configured to display a team viewdashboard, and an individual view dashboard, as described above withreference to group monitoring device 400. Some differences applicable tosome exemplary embodiments of team view dashboard and individual viewdashboard of analysis device 600 include that the displayed informationmay not be updated in real time when using analysis device 600, that theinformation displayed may span multiple sessions of athletic activity,and that alerts can be created that apply to data across multiplesessions.

Moreover, the team view dashboard and individual view dashboard ofanalysis device 600 may be customizable. Display components (e.g.,photograph 410 of individual 10, list of all individuals 10, locationcomponent 412 showing a map of positions of individuals 10 on playingfield, detailed charts and/or graphs 418) can be added or removed bytrainer 20 so as to create a customized view dashboard, which can besaved and referred to in the future. In some embodiments, customizedview dashboards can be sent to or otherwise used by group monitoringdevices 400, thereby allowing trainer 20 to view real-time data in acustom format.

In some exemplary embodiments, analysis device 600 includes an analysischart view that displays a detailed view of a metric, in for example, achart format or a graph format. Trainer 20 may input desired parametersfor the analysis chart view via input 602. For example, trainer 20 mayinput parameters indicating that the analysis chart view should begenerated to show data for all drills performed by Player A duringAugust 2010. Alternatively, analysis device 600 may show trainer 20 alist of all data entries corresponding to the parameters input bytrainer 20, allowing trainer 20 to select the entries desired to beincluded in an analysis chart view. Trainer 20 may also be given theoption to select a type of analysis chart view. For example, trainer 20may be able to choose from a stacked view, where several charts orgraphs, each pertaining to a different metric, are stacked one above theother; or an overlay view, where multiple metrics are displayed on asingle chart or graph. In some exemplary embodiments, the overlay viewallows trainer 20 to view data from one time period (e.g., current dataor most recent data) overlaid with data from another time period (e.g.,older data) to allow easy comparison of performance at different times.

In some exemplary embodiments, to facilitate analysis of one or moresessions of athletic activity, display 402 of group monitoring device400 or display 406 of analysis device 600 may display an analysismodule, which may include utilities useable to analyze the session ofathletic activity, as depicted in, for example, FIG. 55. Display 602 ofanalysis device 600 may display charts or graphs 618 that displaymetrics comparatively. For example, graph 618 may display heart rate foran individual 10 plotted over a session of athletic activity, or anyother time period. Also displayed plotted on the same graph 610 may beother metrics, for example, training impact and mechanical power ofindividual 10. By plotting multiple metrics on the same graph 618,analysis device 600 may facilitate comparison of these metrics, and mayevidence a correlation that can be useful to trainer 20 in monitoringthe performance of individual 10.

In some exemplary embodiments, as depicted in, for example, FIG. 56,display 602 of analysis device 600 may display outlier analyses 620 forcomparing metric information of one or more individuals with one or moreother individuals, and determining when one or more individuals haveachieved a particular metric value that falls outside a baseline value.Outlier analyses 620 can be presented in a variety of ways, and can beuseful in presenting data for multiple individuals 10 in a context thatfacilitates comparison of individuals 10. In some exemplary embodiments,a bar graph 622 showing percentage or value above or below an average(or other baseline) for a metric may be displayed. In some exemplaryembodiments, a star graph 624 showing percentage or value of a varietyof metrics for one or more individuals 10 may be displayed.

In some exemplary embodiments, analysis device 600 can recalculate pastdata based on new algorithms, thereby refining metric calculations ordefining new metrics. In some exemplary embodiments, analysis device 600can apply new alerts to past data. Such features can be useful totrainer 20 by facilitating historical investigation and analysis of dataof individuals 10.

In some exemplary embodiments, analysis device 600 can be used bytrainer 20 to predict future performance of individuals 10. Appropriatealgorithms can be applied to past data that generate predictions of dataof a future session for a particular player or group. For example, if aperformance trend is recognized, it can be predicted that that trend maycontinue in a future session of athletic activity. Trainer 20 can usethis information to inform decisions regarding future sessions ofathletic activity.

In some exemplary embodiments, as depicted in, for example, FIG. 57,group monitoring device 400 may include a report module, which mayinclude a report generator 403 that allows a user to generate reportsbased on data and metrics of individuals 10. Reports can be predefined,or can be customized to generate desired information. A variety of typesof reports can be generated, for example, individual player summaries,reports designed for a head coach, reports designed for a coach of asub-group of a team (e.g., a goalie coach), daily performance updatereports, injury reports, session summary reports, and team conditionreports. For example, as depicted in FIGS. 58 and 59, a dailyperformance update may include information regarding top performingindividuals 10. Such a daily performance update may include listings 405showing individuals 10 that are top sprinters, are top power producers,have highest efficiency, and have top distance. In some exemplaryembodiments, past reports can be saved and accessed from a past reportsmenu 401. Such a daily performance update may also include a team chart407 showing present information for a group of individuals 10 making upa team. Team chart 407 may further indicate differences in the displayedinformation that may exist between the displayed information andinformation displayed in previous reports, thereby indicating changes inthe performance of individuals 10.
